TYPE-WRITING MACHINE.

Application filed August 22, 1913. Serial No. 786,107.

To adieu/m it may] concern Be it known that I, ARTHUR J. BRIGGS,

I citizen bf the Unitedstates, and residentof Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- VVriting Machines, of which the following is-aspecification.

My invention relates to typewriting machines, and more particularly to line s'pacing mechanism.

The main object of the invention, generally stated, is to provide line spacing mechanism which is simple in construction, inexpensive to manufacture and which is eificient in use. 0

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of rts and combinations of devices set forth in the following description and particylla'aly pointed out in the claims.

In the accompanying drawings, Figure l is a fragmentary front elevation, with parts sectioned away, of-the right-hand end of a carriage equipped with the line spacing mechanism of my invention. Fig. 2 is a plan view of the same with parts broken away. Fig. 3 is a detail fragmentary perspective view showin the line spacing pawl, a part of the hand l associated oa "ts. Fig. at is a detail end view of .the platen and some of the associated parts." Fig. 5 is an end view of the parts shown in Fig. '2 as the same are seen when looking in the direction of the arrow in Fig. '2.

rota-tive platen 6 is carried by the platen shaft and has its right-hand platen head 7 formed with crown ratchet teeth 8 to constitute a line spacing wheel for the platen.

The teeth"8 project to the right from the outer side or end of the platen head 7.

A roller detent 9 is adapted to bear against the teeth Slof theline spacing wheel to maintain the platen against accidental Specification of Letters Patent.-

displacement from the line space position to which it may be moved. This roller detent is mounted on a carrier which is desi "ated as a whole by the reference numeral 0 and consists of a bracket arm 11 on which the roller detent is mounted and an integral bearing sleeve 12 whieh surrounds the tie- -:rod 3 and is adapted to move longitudinally thereon. The bracket arm 11 is extended forwardly at 13 where it is slotted,- as at 14, to receive a pin 15 which projects in wardly from the right end plate "2 of the carriage The pin and slot connection thus established between the member 10 and the right-hand end plate of the carriage enables the member 10 to receive a sliding movement along the tie-rod 3 but preventssaid member from turning on the rod; A

coiled expansion spring 16 surrounds the rod 3 and bears at one end against the right-hand end plate 2 of the carriage and at its opposite end against the sleeve 12. The force of this spring is therefore exerted to force the member 10 to the left and to force the detent roller 9 into engagement with the teeth of the line spacing wheel.

The line spacing devices for transmitting movement to the line spacing wheel consist in the main of two parts, one a line spacing pawl, designated as a whole by the reference numeral 17, and the other a sheet metal line spacing lever, designated as a whole by the reference numeral 18. As best shown in Fig. 3, the line spacin pawl comprises an engaging nose 19 whic projects from a hub-like portion 20 connected to or formed as a part of a sleeve 21. This latter surrounds the platenshaft 5 andlr'eceives a bearing thereon for movement lon-- gitudinally of the shaft and also around the axis thereof. The sleeve 21 extends on opposite sides of the member 2-0 and forms trunnion-like projections. From an ins ec tion of Fig. 1 it will be seen that theiefthand end portion of this sleeve is received in a chamber 22 formed in the right-hand platen head, whereas the right-hand end of the sleeve 21, in the normal position of the parts, abuts the inner face of the righthand end plate 2 of the carriage. The pawl is thus supported and guided in its rotative movement around, and its sliding move ment along, the platen shaft. A pin 23 projects from the pawl on theside thereof opposite the engaging nose 19. and is adapted to be received in .a slot 24 formed in an arm 25 which of the hand lever 18.

The hand lever 18 is sheet metal and is provided with a hooklike finger piece 26 and with. a yoke-like portion 27. The yoke-like end portion of the hand lever provides two parallel bearing arms 28 and 29. A shouldered pivot screw 30 extends through a bearing opening in the arm 28 and is received at its threaded end in a tapped opening in the right-hand end plate 2 of the carriage. The other parallel arm 29 of the lever is received in a horizontally disposed slot 31 formed in the end plate 2. A vertically disposed pivot pin 32 extends into an opening in the end plate 2 and passes through a bearing opening in the arm 29. The pivot'pin 32 and shouldered screw 30 thus constitute a pivpreferably made of otal connectionfor the hand lever and afford a substantial support for the hand lever on the carriage, the points of pivotal connection of the two arms 28 and 29 being widely separated and the arm 29 being guided in the slot 31 in the end plate. A coiled spring 33 surrounds the shoulder screw .30 and is fixed at oneiend, as at 34, bybeing seated in an opening in, the end plate 2. The opposite end 35 of the spring bears against a headed pin 36 which extends downwardly from the lower'side of the forwardly projecting lever arm of the hand lever 18. The force of this spring is exerted to normally maintain the hand lever 18 in the position shown in Fig. 2; the lever being limited in its movement in this directionby the arm 25 abutting a wall 31 0f the slot 31, as shown in Fig. 2. The arm 29 of the hand .lever is formed With a projecting stop 37 which of the lever away from the normal position, when a double line space movement,.indicated by the arrow a in Fig. 4, is being effected, the stop 37 will cooperate with the outer face of the right-hand end plate 2 ot the carriage to limit the movement of the I hand lever to the right, and thus determine the extent of line given the platen.

I have made spacing, indicated by the arrow 6 in Fig. 4, by providing a pivoted sheet metal stop member designated as a whole by the reference numeral 38; This stop member is pivoted on a shouldered pivot screw 39 to the spacing movement to be end plate 2 of the carriage, and isformed with a finger piece 40 by which it may be readily turned to the full line position represented infFig.

5. A stop projection 41 extends to the right.

from the plane of, the stop member and the dotted line position e stop portion 41 will be shown inFig. 5, th

path of the stop or engagremoved from the projects from and forms part i will be interposed limits the movement which is sufiicient to provision for single line on its pivot from the dotted .this stop constitutes ing portion 37 on the hand lever, thus enabling the hand lever tent of Jnovement for double line When, however, moved to the full line position, the part 41 in the path of the member 37, thereby limiting the movement of the hand lever so as to afford only a single line space feed of the platen. I have also provided the stop member 38 with a foot piece or projection 42 which limits the for ward movement of said member to operative position by cotiperating with the traverse bar 1 of lines in Fig.5.

In order to retain the member 38 in either to receive its full exspacing. the. stop member 38 is* the carriage, as shown in full of the two positions 'to which it may be i moved, I have formed such member with a laterally extending projection 43 which, as shown in Fig. 2,v is bent up from the sheet metal from formed. This projection gage above the contracted right-hand is adapted to enend plate 2 when the parts are in the full line position represented in Fig. '5, and is adapted to engage below the lower portion of the end" i the dotted line edge of said contracted plate when the parts are in which the member 38 is portion 44 of the t position thus holding the member .38 I? against accidental displacement from either of the two positions to which it ma adjusted. It wil sheet metal member 38 is sufficiently flexible to afford a slight lateral deflection of said memberfto enable the from one side to the portion 44 of the end projection 38 'to pass other of the contractedplate.

be! I be understood that the expansion spring 45 surrounds the I right-hand end portion of the sleeve 21 and I v 1'05 plate of the carriage, and at its opposite end i against a circumferential shoulder 46 formed bears at one end against the right-hand end on the sleeve 21-.- The force of this spring'is exerted to move the ving' wheel, by shifting thepawl i-ilong the line spacing pawl to the left and'into engagement-with the {line spac-' platen shaft. The force of this spring, howa I i ever, is resisted, inthe normal position of the parts, by the power of the spring 33 overcome the power of the spring 45. Thus the wall 47 of the slot 24 in the hand lever the pin 23 of the pawL- The opposite side of the pin, in the normal position of theparts, is engaged by a fixed stop or guide. .48 wh' ich is' in the nature of a sheet metal bracket secured to the right-hand end plate 2 by a screw 49; The engagin a cam ace against which the pin 23 of the pawl is adapted to bear and against which 1t is forced by the engages on one side of face 50 of crank arm 25 of the hand lever, under the power of the spring 33 exerted thereon. It will be understood that as the hand lever is shown in 2, the engaging face 47 of the slot in the hand lever will assume a position which is more nearly parallel with the of the platen and will enable the pawl to slide along the platen shaft, under the force of its spring 45, and into engagement line spacing wheel. This sliding movement of the pawl takes place at the first portion of the movement of the hand m lever from its normal position and is sub stantially a rectilinear movement. When, however, engagement its-effected between the line spacing pawl and the line spacing wheel a rotative movement of the pawl is selected by the further movement of the hand lever to the right. This rotative movernmt of the pawl is effected by a direct acticnthereonof the hand lever through the and slot connection 23-24; between the 29 two. In returnmovement of the partsengaging wall a? of the slot 24: in the lever forces the pin 23 back into enentith the cam face 50 of the stop 4.8 and causes the pawl to be the platen shaft to the normal iaving been hereinbefore extthe powerof the spring 38 is overcome that of the spring 45. regoing description it will be iat while the movement of the one platen shaft into engagement with a spacing wheel is actually effected by he spring 45, nevertheless this movement of the pawl is controlled by the (5 hand 1 it will seen that the hand lever swings horizon? lly and in its movement from normal to operative position the finger piece of the hand ver moves from left to right. It will b stood, therefore, that pressure exerted "Lie operator from left to right on the fin piece 26 is effective to produce a line spac movement of the platen and is also effe e to move the carriage from left/to right to begin a new line of writing. it will also be seen that the line spacing pawl in fact a lever of the first. order controlled directly by the hand lever, which is lilwise a lever of the first order; that one of the hand lever 18 bears directly 23 of the lever 17 and controls st mentioned lever for along the platen shaft as well as for rotative movement around the axis thereof; and that 55 the walls of the slot 24: in the hand lever are at times so disposed that they constitute cam faces operative on the pin 23 to control the paw t of the pawl longitudinally of the that the operation of the pawl is and positively controlled.

A resentconstruction the line spacand the crank arm 25 of the hand constructed and arranged that they do movement Y L xtend beyond the surface of the l platen, so that the work sheet may svmlwp" and extend around the line-spacing wheel if necessary, and In fact may surround the line spacing pawl and thedevices by which it is actuated up to the right-hand end plate of the carriage. This is a matter of some im porta'nce in that it enables a wider sheet to be employed, without interference from the line spacing devices, than is ordinarily the case for a given length of platen.

It will be understood that the line spacing devices which coiipcrate with the line spacmg wheel and by which a variation in the line spacing movements may be controlled, may be said to comprise in the main three 4 parts, i. 2., the member 17 the hand actuated 8 line spacing lever 18 and the member 38p that the parts 18 and 38 are made of sheet metal and are simple in form, and that the parts maybe readily assembled and are not liable to beideranged or broken. It will be observed,'therfore,that by the present invention I have provided line spacing devices which are simple in construction, in expensive to manufacture, embodying but few parts and most of them made of sheet 9 metal, and that the devices are eflicient and reliable in use.

While from certain aspectsof my invention the part 19 in itself may be regarded as a line spacing pawl, and the partQO- 21-23 may be regarded as a carrier therefor, so that the rigidly ,united parts 19, 20-21--23 may be considered as a combined pawl and carrier, nevertheless from certain other aspects of the invention the parts 19, 20'2123 all preferably formed from a single piece, may be regarded as the line spacing pawl designated as a Whole by the reference numeral 17.

When I refer herein to a combined pawl and carrier I mean that the pawl and the carrier by which it is pivotally supported and carried are rigidly united, or; are in ef feet one part and always move together.

Various changes may be made within the spirit and scope of the invention.

What I claim as new and desire to secure by Letters Patent, is
